LoopDraw: a Loop-Based Autoregressive Model for Shape Synthesis and Editing

arXiv:2212.04981v2 Announce Type: replace-cross
Abstract: There is no settled universal 3D representation for geometry with many alternatives such as point clouds, meshes, implicit functions, and voxels to name a few. In this work, we present a new, compelling alternative for representing shapes using a sequence of cross-sectional closed loops. The loops across all planes form an organizational hierarchy which we leverage for autoregressive shape synthesis and editing. Loops are a non-local description of the underlying shape, as simple loop manipulations …
